HORACE-H. BIGELOW, OF WORCESTER.v MASSACHUSETTS.

The Schedule referred to in these Letters Patent and making part of the same To all whom. it may concern:

Be it known that I, HORACE H. Brannow, of-the city and county of Worcester and State of Massachusetts, have invented certain new and useful Improve-.-

ments in Machines for Heeling Boots and Shoes;

and. I- do ,hei ehy declare'the following to be a full, clear, and exact description of the sanie, reference being bad to-the accompanying drawing forming a part of this specification, in which-- vFigured represents a front view of my improved machine for heeling boots and: shoes;

-'. 3 Figure 2 represents a side view of the same;

Figure 3 represents a central vertical section on Figure 4 represents 'a horizontal section on line C D,fig.1;and

Figure 5 represents a central vertical section of one of-the drivers and dies, shown on an enlarged scale".

To enable those skilled in the art to which my invention belongs to make and use the same, I will proceed to describe it more in detail;

The nature of my invention consists- First, in a spring holdiug-die,as hereafter explained. Second, in the combination, with the spring holdingdie, ot'a driving-stud, as hereafter explained.

'lhird, in the combination, with the holding-die and driving-stud,- of a relieving-spring and adj listing-screw,- ns hereafter explained. I

Fourth, in thecomliinntion, with .a series of holding-dies and driving-studs, ot a rotating plate or disk for supporting thesame, as hereafter set forth. v

, Fifth, in the combination, with the holding-die of a depressing-leverand treadle', as hereafter dscribed. Sixth, in the combination, with the holding-die, driver-stud, and operating plunger, of a swing jackspindle, as hereafter described.

Seventh, in the combination, with the operating plunger and power-dog, ofa bell-crank lever and foottreadle, as hereinafter described.

Eighth, in a machine for heeling boots and shoes,

the parts of which are constructed and combined to- Q gcther substantially as shown in the drawing and hereinafter described.

In the drawing I The part marked 'A is the bed or table of the machine, supported upon the legs or standards A.

B indicates the upright frame, uponwhich is supported the driving-shaft (l,"ccceutric-shaf t 1), and plunger E. The frame B is made-oi the form shown in the drawing, and is provided with a strengthening flange, B, which extends'down the back of the frame, and also across the under side of the bed A.

At the front of the bed-"or table A is arranged a circular plate or disk, F, pivoted at its center to the table A, in a horiontal position, by means of a hollow spindle, (1-.

Supported upon tbedisk or plate F is a series of spring holding-dies Gand driving-studs I. w

The dies Gare for holding the boot or shoe-heels in proper position during the operatiouof attaching them to the boots or shoes; and thedlivingestuds I, which are provided at their upper endswith headplates 0, are for the purpose of forcing in the nails by means of which the heels are secured to the boots or shoes.

The dies G and the head-plates o of the drivers I are made to correspond in shape with. the" heels to be attached, each one of the series being made for a different-sized shoe orboot, or fora different pattern of heel. r Y

The lower ends of the driver-studs I are fitted into holes drilled in the disk Ewhere they are secured in an upright position by means of suitable set-screws,

b, at the edges of the disk F, while the dies 6- are arranged loosely upon the studs I, so that they can rise and fall thereon as required.

The dies G are held in an elevated position, when not otherwis'eacted upon, by means of coiled-wire springs 11, arranged around the studs I, between the dies, G and disk F, as shown in the drawing, the lower portion e of the die-:block being turned down so as to fit into the coil of the spring, to-prevent it from' slipping ont of place.

. -'lhe dies G are made somewhat deeper, than the:

thickness'of the heels, so that their upper edges form a guide against which to rest the upper of the boot or shoe while attaching the heel.

as' shown at 2, to allow space for the shank of the boot or shoe.

Above the disk F, and directly over the die at its front side, is arranged the vertical plunger E, sup-- ported by the upright frame B, and operated upand down by a dog, H, in connection with an eccentric,

' J, upon the eccentric-shaft D, at the upper part of said frame.

The plunger E has attached to its lower end, by means of a hinge-joint, K, a swing jack-spindle, L, for holding the boots or shoes while heeling them.

The lower end,of the jack-spindleL is provided with a steel head, j, suitably rounded to fit the interior of the boots or shoes, while near the upper end of said spindle L is attached a hand-lever, L, fornished with a handle, L, by meansof which the jackspindle L may be swung forward, as shown in fig. 2,

.or back, as indicated in fig.'3 of the drawing.

Beneath the disk F, at the front of the table A, is

. arranged a device for relieving the machine from injurious strain and shock.' ltoconsists of a cushionblock, M, supported by a strong spring, M, inoased iua hollow cylinder, M beneath the table A.

vLin-the upper side of the cushion-block M is ar- The edge is scalloped out at the front of the die, I
